Percussion Drill Bit - Carbide Tip - 7/16" x 6" is rated

Carbide bit disintegrated in less than 5 minutes
Purchased to secure expanding concrete anchors for a project. Slab 4" thick concrete. Drilled one 4" hole just fine, got to the second and it only made it 3". What? The carbide tip completely disintegrated. The slot where it used to be secured was fused together. Extremely disappointed by the quality of this. For reference a Bosch and Milwaukee were used side-by-side and look great after drilling 4x the number of holes.
